2004 M3 False Alarm! Need HELP!

[JMC Inc]

Hi all...
My 2004 M3 starts to show some problems..
It has to do with the alarm that goes off from time to time.
I cant predict when it goes off but only thing i can recognize is that
the alarm goes off and rings for about 10 seconds and then it
ceases itself. Then I go check to see the car and I find that
the driver's side window is slightly open (almost tilted open so that
you can't really tell difference)

I called the dealershop but the warranty expired and they ask me to
pay $140 just for an hour of labour hour..and it will still be charged
even if they don't find any problems..

So..anyone knows how to fix this problem or what is wrong with this
behavior?

I think it has to do with the door sensor but when I lock the car
the car is locked and alarmed..I think that the window slightly opens
itself..(as it opens and closes itself when door is open and shut)

Thanks for your advice..

sounds like a GM. pay the diagnostic.

thanks, but what's GM stand for?

Most likely, gm ~= to general malfunction.

no general module.

stop being a cheap-o. you have an expensive complicated car. just pay the diag fee and get it figgured out. you cant figgure this out w/o being able to see the alarm counter.... besides the window going down w/ it sounds like a GM issue.

it could be the door latch sensor, the sensor may not be sure if the door is opened or closed...i doubt the gm would just go bad like that, but you'll prolly still have to take it to the dealer and at least have them check the codes
